which the following is f ull, clear, concise, and exact description, reference being haddriiwing, forming e partof this specification.

My invention relates to push buttons.

It has among its objects toprovide improved means or elongating a push button of an electric switch. Other objects and advantages of my invention will hereinafter In order that my invention may be clearly and fully disclosed, I have illustrated sev eral embodiments of the same in the accompanying drawing. it is to be understood, however, that the forms herein illustrated are susceptible of modification.-

Figure I shows a push button operated switch mechanism in position in a fixture and equipped with one form of my invene tion. Fig; 2 shows a detailed view of a push button with an extension ,thereon, the extension bein' shown in section. Fig. '3 shows a. modified forin'of the construction shownin Fig. 2. Fig. 1 illustrates further 'The push buttons 1 of the switch mecha- 4 nisi'n are provided with cylindrical caps or extensions 2, hawng open ends, which are adapted to be slipped over the ends .of the push buttons and attached thereto.

- push In the construction shown in Figs. 1, 2 and 3, theopen ends of the capsare slotted as at 3, and provided with sliding bands or rings l of slightly larger diameter than the diameter of the exterior of the cap. By

z'idjust'ing these bands longitudinally of the cap, the extensions are readily attached to or removed from the push buttons. In order to preventthe 'cafifrom being slipped too far over the end of the push button and to provide asubstantial means for taking up the thrust applied to the end of finer f iihout leaving the strainuipon the holding 1d 1. I- provide the'cap with an r int -rnel head or flange 5, \Vi'lli, in position upon the end in. abuts against the end. eath in app in the extension or pccificatiou of Letters Patent.

slipped over ,the end of the push button. The cap is then locked and securely.- held upon the push butto. sliding the band it along the same. to:. tl.\e'position shown irl. Fig. 1i Obviously a. any desired length in order to adapt it i use in any desired relation. l vhen it de's'iied tozremove the cup; all't-hatit is nec essary to do is to slide the band 'or-ringin' the opposite direction and then withdraw the cap. .7 i i In order that the caps or extensions may: at the same time serve as means for indieating the position of the switch mechanism;

I provide the caps with certaindistinguish 5- push hut-ted cap may oeumde of 6C ing the cap I am able to make the serve as 'xisualindicators by which apejrson' at a glance may determine the. condition oi" the switch. v 1

Fig. 3 shows a modified form of the" con struction shown Fig. 2. "end of the push button is provided with an In this form the annular groove 8 adapted to -re'ceive -oorre V sp'oudingly shaped annular flange or head? upon the periphery ofthe .cap.-- 'As'iin the. construction herctofoie'descrilmd, the cap may be secured to the 'ush hut-tonby means of the sliding ring or and.

l shows a further modified form of. cap wherein the end 10 of the cap is threaded,

and .(mrried upon a correspondinglythreaded portion of the push button, which, if de-. sired, may he made of rcducedcross section. Obviously by ad usting' the cap upon the threaded end of the butthii the length cf the id extension may be varied as desired. By the u"" of my iuvention'l am 'iihle to materiull range ofuse'tiilness For instance, push push buttons of Fe readily adapted to These ie of any l mounted to e u'iile H s W bile I have in this application described several forms ofmy invex' ition in order .to

disclose-the same, I do not restrict myself to the fog-ms herein shown for purposes of ilhistraifion.

What I claim new and desire to secure by Letters Patent of the United States is as follows eompressinv theslotted'end thereoi' upon the and of said button.

2-. In combination, a push button having an annular groove therein, a cylindrical extension capv havinga longitudinally slotted end inclosing the end of said pushbutton, said cap having interior projections fitting in said groove, and a sliding ring carried by 7 said cap for compressing the slot-ted end thereof upon the end of said but-ton.

In witness whereof, I have hereunto subscribed my name in the presenceifof two witnesses. T
